Treatment options for patients with advanced HCC increased by sorafenib, and long-term survival for patients with advanced stage HCC has become possible to some extent. However,development of a more potent first-line novel molecular targeted agent replacing sorafenib and a potent second-line agent after disease progression on or intolerant to sorafenib has been warranted because sorafenib lacks tumor shrinking/necrotizing effects and induces relatively severe adverse events such as hand foot skin reaction. Many agents in the 1 st line and 2 nd line setting were attempted to develop between 2007 and 2016, but all of these clinical trials failed.On the other hand, clinical trials of 4 agents(regorafenib, lenvatinib,cabozantinib, and ramucirumab) succeeded in succession in 2017 and 2018, and their use in clinical practice is possible(regorafenib and lenvatinib) or underway(cabozantinib and ramucirumab). Furthermore, all of 5 clinical trials of combination therapy with transcatheter chemoembolization(TACE) plus a molecular targeted agent failed to date, however, the combination of TACE and sorafenib(TACTICS trials) was reported to be successful and presented at ASCO in 2018. Phase 3 clinical trials of immune checkpoint inhibitors and a combination therapy of immune checkpoint inhibitors and molecular targeted agents are also ongoing, which suggests treatment paradigm of HCC in all stages from early,intermediate and advanced stage, is expected to be changed drastically in the very near future.展开更多

Sorafenib is the only food and drug administration(FDA) approved as first line systemic treatment in HCC. Regorafenib and nivolumab are the only FDA approved second line treatment after progression on sorafenib. We will discuss all potential first and second line options in HCC. In addition, we also will explore sequencing treatment options in HCC, and examine biomarkers that can potentially predict benefits from treatments such as immune checkpoint inhibitor. This minireview summarizes potential treatments in HCC based on clinical trials that have been published in manuscript or abstract format from 1994-2018.展开更多

In the present study, we evaluated the potential of early changes in the time-intensity curve(TIC) of arterial phase on contrastenhanced ultrasound(CEUS) as early imaging biomarkers of lenvatinib efficacy.AIM To evaluate the potential of the early changes in the TIC of CEUS as early imaging biomarkers of lenvatinib efficacy in patients with unresectable HCC.METHODS We analyzed 20 consecutive patients with unresectable HCC treated with lenvatinib from March to November 2018. Tumor response at 8 wk was assessed by computed tomography using the modified Response Evaluation Criteria in Solid Tumors(m RECIST). CEUS was performed at baseline before treatment(Day 0) and on day 7(Day 7), and the images were analyzed in the arterial phase for 20 seconds after the contrast agent arrived at the target tumor. Three perfusion parameters were extracted from the TICs: the slope of wash-in(Slope),time to peak(TTP) intensity, and the total area under the curve(AUC) during wash-in. The rate of change in the TIC parameters between Day 0 and Day 7 was compared between treatment responders and non-responders based on m RECIST.RESULTS The rate of change for all TIC parameters showed significant differences between the responders(n = 9) and non-responders(n = 11)(Slope, P = 0.025; TTP, P =0.004; and AUC, P = 0.0003). The area under the receiver operating curve values for slope, TTP, and AUC for the prediction of responders were 0.805, 0.869, and0.939, respectively.CONCLUSION CEUS may be useful for the early prediction of tumor response to lenvatinib therapy in patients with unresectable HCC.展开更多
